FIELD CROPS, 633 



discusses the increased yields following: an increased weight of seeds in plant- 

 ing beans, and suggests to the breeder the importance of so planning his work 

 as to take the purely physiological factors more fully into account than is 

 generally done. 



Crimson clover: Growing' the crop, J. M. Westgate (U. S. Dept. Agr., 

 Farmers' Bui. 550, pp. 15, figs. 5). — This publication gives the history and pres- 

 ent distribution of crimson clover. Among the requirements for obtaining and 

 maintaining a .stand are mentioned lime and humus in the soil, and inoculation. 

 Methods of seeding in intertilled crops, after early maturing crops, with late 

 summer-seeded annual crops, with other legumes and grain, and alone, are 

 de.scribed, as well as the treatment of crimson clover stands after seeding. 



Corn culture and improvement, C. K. McClelland (Hatcaii Sta. Press Bui. 

 42, pp. 36, figs. 7). — This article summarizes available data as to corn produc- 

 tion and utilization, with a view to inducing greater interest in corn grovi'iug in 

 Hawaii. 



Mosaic coherence of characters in seeds of maize, G. N. Collins ( U. S. 

 Dept. Agr., Bur. Plant Indus. Circ. 132, pp. 19-21). — Results are described of 

 observed mosaic coherence of color and endosperm character (waxy or horny) 

 that was obtained in hybrids between Chinese maize and the common American 

 maize. " In the first exami)le the Chine.se parent having the waxy endos!)erm 

 had a colored aleurone and in the mosaic seed the waxy portion is ovevL-iid by 

 a colored aleurone. In the second example, the waxy parent was white ar'd 

 in the mosaic seed from this cross the waxy portion of the seed is while. In 

 both seeds the form of the colored spot is irregular and the line separating Ihe 2 

 kinds of endos-perm follows the irregular margin of the spot with great pre- 

 cision." 



Maize from the Sudan (Bui. Imp. Inst. [So. Kensington], 10 {1912), No. 3, 

 pp. 38V-.39S). — This pai>er reports an examination of maize which was grown 

 in the Sudan. The medium length of the ears was Sf in., the circumference 

 6i in., and the weight 308.8 gm. The number of rows ranged from 12 to 20. 

 In the heaviest ear the kernels formed 83.8 per cent and in the smallesi ear 87.8 

 per cent of the total weight per cob. A table of analyses shows the composition 

 of Sudan, South African, North American, and River Plate maize. 



Ten years of com breeding, E. D. Funk {Amer. Breeders Mag., 3 (1912), No. 

 4, pp. 295-302, figs. Jf). — This paper discusses the results obtained by the ear-to- 

 row method of corn improvement and points to the performance record as show- 

 ing the superiority of the yield-per-acre unit over the score card as a method of 

 selection. Some of the highest yielding strains of corn have been anything but 

 ideal ears from the standpoint of the score card. It is also noted that a series 

 of experiments .showed that in 6 years out Of 7 the smooth type of com made 

 higher yields than the rough.

 Nel)r. Corn Improvers' Assoc., 3 (1912), pp. 115, figs. 8). — This report gives the
